RESEARCH A CTIVITY ON EXPERIMENTAL ASSESSMENT OF SEISMIC ESPONSE OF MASONRY ARCADES
The analysis of seismic vulnerability of old masonry structures is very hard, especially when already damaged by earthquakes. Modelling of the structure is often very hard and the numerical analysis does not give any realistic information. Therefore the experimental analysis is not only advisable but represent the unique way to improve the understanding of the structural behaviour. Seismic actions cause cracks in the masonry, and as a result the reduction of the stiffness, which implies changes in the dynamic characteristics and apparent non-linear behaviour. These effects can be pointed out by analysing seismic recordings or by means of shake table. In this paper the preliminary results of the analysis of shake table tests are shown, and technical limits and technological failures are discussed.
